Honestly, I have seen no change in battery performance from iOS6 to 7 on my iPhone 5. Not to mention it would probably be at 45% if I just didn't have a 30 minute phone call while surfing the web at the same time.
Wow you got like 11 hours and still have battery left. Crazy.
Yup, got the same usually on iOS6. Yesterday I got 14 hours and had battery life left. You just got to tweak some settings. Now then again in the past hours I've lost 19% but I had a 30 min call while surfing the web, and using wifi.
Your usage is mainly listening to music?
I charged over night and went to 52% with in 60min., WHAT???
Not surer what's up?
